45.System integration and clinical implementation are two other neessary components during the implementation after the system is physically connected.

9.Although there are great differences among diagnostic X-ray machines for different diagnostic objectives,the fundamental structure of X-ray machines is similar ,which consists of X-ray generating device,X-ray imaging device and X-ray auxiliary device.

42.In contrast to radiologic procedures, which determine the presence of disease based on
structural appearance, nuclear medicine studies determine the cause of a medical problem
based on organ or tissue function physiology.

13.The flat panel detects the X-rays that have passed through the patient’body, converts them into electrical signals using X-ray scintillation effects, and sends the signals (digital image signals )to the digital radiography system.

29.After the scan is completed ,you can adjust the window center and width for optimal viewing of the image.

44.At the present time, the eriphasis of nuclear medicine studies is more on its function and
chemistry than anatomic structure.

48.A full PACS should provide a single point of access for images and their associated data. That is, it should support all digital modalities, in all departments, throughout the enterprise.

47.The client fills in the C-FIND request message with the keys that should be matched. E.g. the patient ID.

19.Therefor ,like the conventional X-ray images , the shadow indicates low absorption area , namely the low density area such as lungs ; and the bright indicates the high absorption area, namely the high density area ,such as bone.

49.DICOM enables the integration of scanners, servers, workstations, printers and network hardware from multiple manufacturers into a picture archiving and communication system PACS.
